Air Lift 1000
Installing the Air Lift 1000 System
IMPORTANT NOTES
If your vehicle is equipped with vibration dampers between the turns of the coil, it is necessary that these be removed before installing the air springs. Their function will be replaced by the air spring. Some midsize GM vehicles have a solid cup located on the lower spring seat which will not allow the airline to exit the coil. It is necessary to remove this cup before installing the air spring.
For Suburban, Tahoe, Yukon, TrailBlazer, Envoy, Bravada, Avalanche, Hummer H, Pathfinder and Escalade it will be necessary to trim the rubber isolator at the top of the coil spring to ensure adequate valve stem clearance. Also, some models have a plastic vibration damper snapped around the coil of the coil spring (blue in color. This must be removed before inserting the spring.
GETTING STARTED
Before beginning the installation, check the clearance from coil spring to exhaust. It is
common in your application for the exhaust to be very close to the coil. If there is less than
2” of clearance, you will need to install a heat shield (if supplied).
1. Jack up the rear of the vehicle or raise on a hoist. Support the frame with safety stands. Lower the axle or raise the body of the vehicle until the suspension is fully extended (fig. 1).
